You said fccid was almost the same, on this one I think it’s 100% the same! I think there is a 5c and 5d. I got the 5d which is the same as the tesla unit!

I ended up returning VW HomeLink back to seller once I found it doesn't work with Tesla. I spent some time on FCC website compering PCBs on both HomeLink's and visually hardware looked the same . My guess was Tesla uses some kind of handshake command to initialize it and could be AUDI/VW HomeLink firmware was different.

Here is another one on eBay: 2017-2018 AUDI S4 A4 HOMELINK GARAGE DOOR OPENER MODULE OEM 4M0907410A #115 | eBay
BINGO, that's a ADHL5C. Both the Tesla A and B models are ADHL5D and I found a Audi/VW ADHL5D model: 2018 - 2022 AUDI MODELS GARAGE OPENER CONTROL MODULE OEM 4N0907410C
Looks like the C came out before D by a year or 2. It could even be a different pinout!

model number looks the same but different Gentex part number. Would be interesting to see if it works with Tesla. My guess is the homelink firmware is different and hence why different Gentex part numbers. I’ll be surprised if audi/vw and tesla share the same protocol.
You might be right. I thought you had a hl5c which I would assume is different then hl5d since I got a hl5d I assume it’s the same as the tesla one but your right there might still be a firmware difference! We’ll soon find out. I’ll make sure to setup the mobile appointment at work instead of home so they don’t try to program the garage find it not working and turn it back off!
I have’t found that to be true on my Model 3.
If I’m facing away from the house it will not open my garage door reliably. I wonder if the MY has it more centrally located?

Ugh tried bringing this in today but afte. A confusing
There in almost the same spot. The model 3 actually has it right behind the bumper facia. The Y has it behind the facia and bumper bar. It’s sits in front of the front tub.
That may be fixable if the firmware is indeed different. Based on the pictures on the github page, the microcontroller is a pic24ep256gp. Debuggers / programmers appear to be pretty cheap for that microcontroller. So it might be possible to dump the firmware from a Tesla module and flash it to a VW module.
Also looking at the board for that HL5 module, it's clear that pin 4 is an extra ground. Not sure what pin 5 is going to, but probably same function as pin 4 on the HL4 module.

You only need gnd pos lin you don’t need other wires! Those are for cars that blink lights and stuff!
Weird I found the mount. But I cannot find the five pin connector anywhere. The only thing that looks remotely like it is this seven pin connector in the middle of the frunk pretty much directly underneath the latch and behind the button on the Frunk tub.
The car is built February 22
Somewhere I looked and I forget where it said Tesla model ylong range 2021 but being built in February 22 maybe it’s a 22 model.

That's infuriating. I mean, congrats haha, but I've tried twice to schedule appointments and they cancelled them both saying "we confirmed with management it's just impossible to activate a reinstalled homelink module". I don't even know what to do at this point.
